very nice series! composed really well, reflections w/ the trees gives it a nice effect... although most of the pics doesnt have that sweet spot in them; thats just me... maybe thats the effect that u wanted to capture... #2 is the best pic for me...

Thanks for your very helpful comments. I fully agree: the sweet spot is not ideal on any of these pics. I am still a beginner and try to find out how to be more 'on the spot'. I find it particularly difficult to find the sweet spot when tilting and shifting. Any tips how I can improve my technique?

same here, a beginner! its really hard to find that sweet spot w/ the tilting/shifting... i think its really helpful to use a tripod & the view finder in ur camera when taking pics w/ lensbaby... thats just me!
